6 Claims.

Our invention relates to a new and useful im provement in an accordion key board and particularly the mountings therefor. With accordions as now constructed, the key board generally extends at right angles to the bellows and at right angles to the stop board. This necessitates the holding of the accordion in such a position that the players arm is crooked around the key board in order that the fingers may reach the keys.

It is an object of the present invention to provide an accordion having the key board so arranged and constructed that it extends parallel and substantially in alignment with the stop board so that the key board is easily accessible to the player without necessitating the crooking of the arm and so that the key board itself may be brought into snug engagement and lie closely vagainst the body of the player while the accordion is being used.

Another object of the invention is the provision in an accordion of a key board mounting so arranged and constructed as to permit of a maximum sound chamber directly beneath the stop board and above the bellows.

Another object of the invention is the provision of a key board mounting so arranged and constructed that the reed blocks may be mounted in inclined position, thus faciliting the assembly and improving the tone of the instrument.

Another object of the invention is the provision of a key board mounting on an accordion so arranged and constructed as to render the accordion most compact.

Another object of the invention is the provision in an accordion of a key board having side rails provided with tapered ends at one end so as to retain the key board in parallel relation to the stop board and at the same time eliminate any objectionable shoulders which might interfere with the operator when using the instrument.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawings which form a part of this specication, and in which,

Fig. 1 is a perspective view of an accordion showing the invention applied.

Fig. 2 is a. sectional view taken on line 2-2 of Fig. 1 and Fig. 3.

Fig. 3 is a, sectional View taken on line 3-3 of Fig. 1.

Fig. 4 is an end elevational view of the invention, showing it applied.

As shown in the drawings the invention is used with an accordion having a stop board I in which are formed the openings 8, extending downwardly from which are channels 9 formed on opposite sides of the reed blocks I0. Positioned over the openings 8 are the stops II, each of which is connected by a rod I2 to a key I3. These keys are pivotally mounted by means of a` rod I4 to the key board which comprises a base I5, a front rail I6 and side rails I'I and I8. The rod I4 ex tends through the rail I'I and into the rail I8. It will be noted, therefore, that we have constructed a key board mounting which extends parallel to and in substantial alignment with the stop plate or stop board. It will be noted that the side rails II and I8 are tapered at their forward ends by the formation of the beveled surfaces I 9 and 20. In this formation it will also be noted that the reed blocks I0 are inclined to the stop plate or board 'I and that there is a compartment or chamber 2I, beneath the stop board or plate 'I and enclosed by the rear wall 22 and the side walls 23 and 24. In this manner we have obviated the extension of the key board at right angles to the stop board I and we have made it possible for the advantages sought to be obtained. Particularly is it to be noted that in this arrangement the key board will lie snug against the body of the operator and it will not be necessary to crook the arm in order to extend into operative position, relatively to the key board.

While we have illustrated and described the preferred form of construction, we do not wish to limit ourselves to the precise details of structure shown, but desire to avail ourselves of such variations and modications as may come within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In combination, an accordion stop plate; and a key board mounted on said accordion and extending in a plane parallel to and substantially in the plane of said plate.

2. In an accordion, a stop plate; a key board; and a frame for supporting said key board and retaining the same extending substantially parallel to and in the plane of said stop plate.

3. In an accordion, a box-like structure; a stop plate on one side of said structure; a frame mounted on said structure and projecting outwardly therefrom and extending in a plane substantially parallel to the plane of said stop plate.

4. In an accordion, a stop plate; a frame extending outwardly from said stop plate and comprising side rails, the ends of said side rails, adjacent said plate, being tapered, said frame lying in substantially the same plane as said stop plate; and a key board mounted in said frame.

5. In an accordion, a stop plate; a frame extending outwardly from said stop plate and lying l0 in substantially the same plane as said stop plate;

and a key board mounted in said frame.

6. In an accordion, a box-like structure having oppositedly disposed Walls; a stop plate on said structure extending diagonally thereof and forming a closure at the ends of said Walls; and a key board mounted on said structure and projecting outwardly beyond one side thereof and lying in substantially the same plane as said stop plate.
